Is there no one to answer this?
Corroded or loose battery connections, loose alternator drive belt, defective alternator, or dead cell in the battery.
No, the alternator will not charge the battery with the negative terminal loose.
Certainly, a loose wire on the car battery can cause the car not to start.
No. A loose battery connector will cause problems drawing power from the battery to start the vehicle, and it may present a bit of a problem charging it (but that is not likely because the charging current is low compared to the starting current). If you have a loose connector and the battery goes dead, clean and tighten your battery terminals and start making some checks. The loose connector will not cause your battery to go dead.
Check for loose or corroded battery cables Check for loose connection at starter or ground
Can be loose or corroded battery connections, loose drive belt, or the alternator is failing.
Check for a loose or corroded ground or battery cable Check for a loose or corroded ground or battery cable
The red battery light indicates that the battery is not rceiving sufficient charge. Look for a loose belt or loose/dirty battery cable connection, or have the alternator and/or battery checked.
Yes. If it is loose on the side that comes from that alternator, then the alt. is not getting the opportunity to charge the battery. So basically you're running your car on pure battery and it will go dead accordingly
Have the charging system checked. Possibly loose or corroded wiring, a loose alternator belt, or a bad alternator.
COmputer, loose battery, defective battery/volt amps or loose wiring harness/ wires grounding out somewhere
Loose alternator drive belt or loose or corroded battery cables. The battery itself may also be bad.
